推荐答案

使用 NSURLRequest 对象检索此地址处的数据:

Use an NSURLRequest object to retrieve the data at this address:

http://download.finance.yahoo.com/d/quotes.csv?s=AAPL&f=sl1d1t1c1ohgv&e=.csv

使用 [NSString stringWithFormat:] 将 AAPL 更改为您要使用的股票代码.检索到的数据采用 CSV 格式，因此您需要对其进行解析以获取所需的各个值.这可以在这个简单的例子中完成，使用 [NSString componentsSeparatedByString: @","] 来检索一个可以使用两个循环解析的数组.

Using [NSString stringWithFormat:] to change the AAPL to the stock ticker you want to use. The retrieved data is in CSV format so you will need to parse that to get the individual values you require.
